<script type="text/javascript">
    
    // Instantiate the parameters to pass to the SWF.

	// The scale="noscale" specifies that the swf is to

	<h2 class="first">Advanced SWF Utility Example</h2>

<p>In this example, we demonstrate how to embed a SWF on a page, pass it configuration parameters, and interact with it via ExternalInterface and the corresponding YUIBridge library in Actionscript.</p>

<p>First, include the following JS source files:</p>	
<textarea name="code" class="html" cols="60" rows="5">
<!-- Dependencies -->
<script type="text/javascript" src="http://yui.yahooapis.com/2.8.1/build/yahoo-dom-event/yahoo-dom-event.js"></script>
<script type="text/javascript" src="http://yui.yahooapis.com/2.8.1/build/element/element-min.js"></script>

<!-- Source files -->
<script type="text/javascript" src="http://yui.yahooapis.com/2.8.1/build/swf/swf-min.js"></script>
</textarea>

<p>Next, create a container where the SWF will be placed. The size of the container will be the size of the SWF (in this case, we set it to 400 by 200 pixels). The current content of the container is what will be displayed if there is no Flash installed on the user's machine, or if the version of the Flash player installed does not match the minimum required.</p>

<textarea name="code" class="html" cols="60" rows="5">
<div id="swfContainer" style="width:400px;height:200px">
	The version of the Flash player installed on your computer is outdated. Please download and install the newest version.
</div>
</textarea>

<p>Now, create an object with the necessary parameters to pass to the SWF. In this case, we specify the minimum version of Flash player required, whether to use the ExpressInstall capability of the Flash player, and a few SWF-specific fixed attributes, namely the "scale" attribute, which specifies whether to shrink or stretch the Flash content to fit the viewport (in our case, no shrinking or stretching is allowed), and the "salign" attribute, which specifies how to align the content in the viewport (in our case, we align it to top left). We also specify the value for the "allowScriptAccess" parameter as "always", which allows the SWF to make calls to Javascript functions, and vice versa. In addition, we pass some FlashVars -- arbitrary variables which, in our example, will be displayed by the SWF:</p>
<textarea name="code" class="html" cols="60" rows="5">
var params = {version: 9.115,
	          useExpressInstall: false,
	          allowScriptAccess: "always",
	          fixedAttributes:
			  {scale: "noscale", salign: "TL"},
			  flashVars: 
			  {foo: "One", bar: "Two"}
			 };
</textarea>


<p>Next, we create an instance of the swf and pass the parameters:</p>
<textarea name="code" class="html" cols="60" rows="5">
var mySWF = new YAHOO.widget.SWF("swfContainer", "assets/SWFExampleAdvanced.swf", params);
</textarea>

<p>Next, we subscribe to the swfReady event, which fires when the SWF has been instantiated and becomes available for communication with Javascript (if the swf is using the YUIBridge library):
<textarea name="code" class="html" cols="60" rows="5">
mySWF.subscribe("swfReady", testFlash);
</textarea>

<p>We also subscribe to the textAdded event, which the SWF dispatches when an addText method has been called on it:</p>
<textarea name="code" class="html" cols="60" rows="5">
mySWF.subscribe("textAdded", logTextAdded);
</textarea>

<p>Next, we specify the handler that is called when the "swfReady" event fires (because of the subscribe() call above). The handler calls a method on the swf called "addText", and passes a string value to it. (the method is exposed by the SWF using the YUIBridge library):
<textarea name="code" class="html" cols="60" rows="5">
function testFlash () {
	mySWF.callSWF("addText", ["Some sample text\n"]);
}
</textarea>

<p>Finally, we also add a handler for the "textAdded" event, which the SWF fires when its "addText" method has been called:</p>
<textarea name="code" class="html" cols="60" rows="5">
		function logTextAdded () {
			YAHOO.log("Text has been added to the SWF");
			alert("Text added!");
		}
</textarea>
